[0052] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0053] Based on the problems mentioned in the above background technology, in the related art, the vehicle limp mode is a protection mechanism that is automatically activated when the vehicle control system detects a fault, with the purpose of preventing further damage and ensuring that the vehicle can safely drive to the nearest maintenance point. This mode is usually triggered by the vehicle's electronic control unit or gearbox. When the system detects problems with key components, such as sensor failure, gearbox problems, low battery, etc., the limp mode will be activated. In limp mode, the performance of the vehicle will be limited. For example, the engine's output power will be reduced, the accelerator pedal may fail, and the vehicle speed will be limited to a lower level. Therefore, when the vehicle is in limp mode, it will seriously affect the driving experience of the driver and passengers.

[0054] See also Figure 1 , the present application proposes a control method for a drive system, comprising:

[0055] Step S1: when the transmission device is in an abnormal state, determining a target torque that the transmission device can transmit;

[0056] Step S2: Control the output device to output an output torque not greater than the target torque.

[0057] The output device is transmission-connected to the transmission device, and the output device can output power to the driving wheels through the transmission device.

[0058] In addition, the drive system can also be applied to other equipment besides vehicles. For example, in one embodiment, the drive system can be applied to industrial equipment, including construction machinery, logging equipment, underground mining equipment, lifting equipment, etc.

[0059] In the technical solution of the present application, when the transmission device is in an abnormal state, the target torque that the transmission device can transmit can be determined, so that the output torque of the output device is controlled not to be greater than the target torque. On the basis of ensuring that the transmission device is not easily damaged, the output torque of the output device is transmitted to the drive wheels through the transmission device to avoid obvious functional degradation of the vehicle, thereby improving the driving experience of the driver.

[0060] See also Figure 2 In some embodiments of the present application, step S2 includes:

[0061] Step S21: Control the output device to output an output torque that matches the target torque.

[0062] That is, in this embodiment, when the transmission device is in an abnormal state, the target torque that the transmission device can transmit can be determined, so that the output torque of the output device can be controlled to be equal to the target torque. On the basis of ensuring that the transmission device is not easily further damaged, the output torque of the output device is transmitted to the drive wheels through the transmission device, thereby avoiding obvious functional degradation of the vehicle and improving the driving experience of the driver.

[0063] In some embodiments of the present application, the transmission device includes a gearbox; the abnormal state is that the gearbox's shift lever 1 cannot be shifted to the set gear position; wherein, the gearbox's shift lever 1 cannot be shifted to the set gear position, which will cause the shift fork connected to the shift lever 1 to be unable to shift the gear in the gearbox to the set position, so there may be a situation where the gears are not fully engaged, and at this time the transmission device cannot normally transmit the transmission torque that matches the corresponding set gear position.

[0064] In step S1, the step of determining the target torque that the transmission device can transmit includes:

[0065] Step S11: determining the current position information of the gearbox lever 1; and

[0066] Step S12: determining the target torque that can be transmitted by the gearbox according to the current position information of the gearbox shift lever 1.

[0067] That is, in this embodiment, after the lever 1 cannot be moved to the set gear position, the current position information of the lever 1 of the gearbox is obtained and confirmed, that is, the current position information of the lever 1 is related to the meshing condition of the gears in the gearbox, and then the target torque that the gearbox can transmit at this time is calculated.

[0068] Among them, the current position information of the gearbox lever 1 can be obtained by starting detection and obtaining when the gearbox is in an abnormal state; or when the vehicle is powered on, the position information of the gearbox lever 1 is obtained at intervals or in real time to obtain the current position information of the gearbox lever 1 when the gearbox is in an abnormal state.

[0069] See also Figure 3 to Figure 4 In some embodiments of the present application, when the gearbox is in a normal state, the movable distance of the lever 1 when the lever 1 is moved to the first gear is S1, and when the gearbox is in an abnormal state, the movable distance of the lever 1 when the lever 1 is moved to the first gear is S2, wherein S2<S1, that is, at this time, the gear position of the gearbox cannot be shifted into place, and at this time, the current position information of the lever 1 of the gearbox can be obtained and determined.

[0070] In some embodiments of the present application, the position of the shift lever 1 of the gearbox can be detected by a sensor to obtain the position information of the shift lever 1 of the gearbox.

[0071] In some embodiments of the present application, step S12 includes:

[0072] Step S121: Detecting the positional relationship between the current position of the gearshift lever 1 and the set gear position; and

[0073] Step S122: determining the target torque that can be transmitted by the transmission according to the positional relationship between the current position of the shift lever 1 of the transmission and the set gear position and the maximum transmission torque corresponding to the set gear position.

[0074] That is, in this embodiment, when the vehicle is in a normal state, the maximum transmission torque that can be transmitted by the set gear is a constant value. When the drive system is in an abnormal state where the gearbox lever 1 cannot be shifted to the set gear, the target torque that can be transmitted by the gearbox is calculated based on the current position information of the lever 1.

[0075] It is understandable that when the drive system is in an abnormal state where the shift lever 1 of the gearbox cannot be shifted to the set gear position, the target torque allowed to be transmitted by the transmission system may also be different if the current position of the shift lever 1 is different.

[0076] In some embodiments of the present application, when the vehicle is in a normal state, the maximum output torque that can be transmitted by the set gear is T0. When the lever 1 cannot be moved to the set gear, the target torque T1 that the gearbox is allowed to transmit is calculated based on the current position of the lever 1, wherein T1 is equal to k*T0, k is a coefficient less than 1, which is determined by the hardware structure of the vehicle.

[0077] In some embodiments of the present application, the transmission device includes a clutch, and the abnormal state is clutch wear; wherein, the transmission device connects / disconnects the power input of the output device through the clutch. If the clutch is worn, it will affect the power transmission efficiency and cause damage to the clutch when the output torque of the output device is greater than the target torque that the clutch can transmit, such as causing the clutch to overheat or burn out.

[0078] In step S1, the step of determining the target torque that the transmission device can transmit includes:

[0079] Step S13: determining a target wear state of the clutch;

[0080] Step S14: Determine the target torque that the clutch can transmit according to the target wear state of the clutch.

[0081] That is, in this embodiment, after the clutch is worn, the target wear state of the clutch is acquired and confirmed, and the target wear state of the clutch determines the value of the target torque that the clutch can still transmit.

[0082] In some embodiments of the present application, the position of the clutch booster piston may be monitored by a displacement sensor to determine the wear condition of the clutch.

[0083] In some embodiments of the present application, the wear state of the clutch can be divided into multiple different levels, and the control method also includes obtaining the correlation between the wear states corresponding to the multiple different levels and the target torque that the clutch can transmit.

[0084] Based on the correlation relationship, the target torque corresponding to the target wear state can be determined.

[0085] In some embodiments of the present application, the output device includes a motor.

[0086] Step S2 comprises:

[0087] Step S22: Control the input current of the motor to control the motor to output an output torque not greater than the target torque.

[0088] Among them, in the motor, there is a proportional relationship between the input current of the motor and the output torque of the motor. By controlling the input current of the motor, the output torque of the motor is controlled to be no greater than the target torque.

[0089] In addition, there is no restriction on the method of controlling the output torque of the motor, and it can also be through adjusting the supply voltage and frequency control, vector control, etc.

[0090] In some embodiments of the present application, the output device includes a motor.

[0091] Step S2 comprises:

[0092] Step S23: Control the opening of the throttle valve of the engine to control the engine to output an output torque not greater than the target torque.

[0093] Among them, in the engine, there is a proportional relationship between the throttle opening of the engine and the output torque of the engine. By controlling the throttle opening of the engine, the engine output is controlled to output an output torque not greater than the target torque.

[0094] It is understandable that when the vehicle is a hybrid vehicle and the engine and the motor are in operation at the same time, the engine and the motor can be controlled at the same time to control the output device to output an output torque not greater than the target torque.

[0095] In some embodiments of the present application, the control method further includes:

[0096] Step S4: Detecting the throttle or electric switch opening;

[0097] Step S5: If the current output torque of the output device that matches the throttle or throttle opening is not greater than the target torque that the transmission device can transmit, the output device is controlled to output at the current output torque;

[0098] Step S6: If the current output torque of the output device matching the throttle or throttle opening is greater than the target torque transmittable by the transmission device, the output device is controlled to output a torque matching the target torque transmittable by the transmission device.

[0099] That is, in this embodiment, the driver can control the output device to output a torque not higher than the target torque through the throttle or the electric switch, so that the driver can adjust the speed under different road conditions, thereby improving the driver's driving experience; that is, if the current output torque of the output device that matches the throttle or the electric switch opening is not greater than the target torque that the transmission device can transmit, the output device is controlled to output with the current output torque; if the current output torque of the output device that matches the throttle or the electric switch opening is greater than the target torque that the transmission device can transmit, the output device is controlled to output with the torque that the transmission device output matches the target torque that the transmission device can transmit.

[0100] The opening of the accelerator or the throttle can be detected by an opening sensor.

[0101] It can be understood that in step S21, if the transmission device is in an abnormal state, the output torque of the output device is a constant value, that is, the opening of the throttle or the electric switch changes, which will cause the output device to output with an output torque matching the target torque.

[0102] See also Figure 5 The present application also proposes a drive system, which includes an output device, a transmission device and a controller. The transmission device is connected to the output device in a transmission manner.
